For 120 years now, the European Social Democrats and Communists celebrate the International Workers Day on the first of May with demonstrative street parades.
In view of the financial crisis, traditional social values - Liberté, égalité, fraternité - and social security,have become relevant issues again.
This year's May Day celebrations in Vienna had a lot of retro atmosphere.
After all, a remarkable number of 100.000 participated in the parade along Vienna's Ringstraße and the final celebration at the Rathausplatz.
